What command do you use to start the server?  If your IP was
33.215.11.2 it would look like:
python manage.py runserver 33.215.11.2:8000

> Do I need to open up port 8000 ?
Yes  Or figure out what port is already open and use that... Also
check firewall status.

Most likely not.

Yes

Re: template newlines

[Python_Junkie]

I think that if you performed the logic to determine if there actually
is something in the interest for that row in the view and
then only pass those components from the view, and not in the template
then your problem goes away.

Connecting to the django app from outside the server

[Python_Junkie]

I have placed my django application on the virtual server from go
daddy.  The application runs  when I remote into the server and run
the web pages with localhost on the 8000 port.

How do I connect to this web page for demonstration purposes when I am
not remoting into the virtual server.

I tried just replacing localhost with the IP address with port 8000
and that does not work.

Do I need to open up port 8000 ?

Is it possibly a permissions issue.

I am presuming that I can continue to use the django light weight web
server for demonstration purposes.

Any assistance would be appreciated.


Thanks in advance

template newlines

[CrabbyPete]

I'm using the django template system for format a text email. I send
it a dictionary and it formats the output. The problem is that it
inserts lots of newlines

Here is the template, and reports is a dictionary that contains an
event and a dictionary of interests

Weekly Contact List For {{date}}
{% for event, interests in report.items %}
{% if interests|length > 0 %}
{{event}}
{% for interest, value in interests.items %}
{{ value }} {% if value == 1 %} lead {% else %} leads {%
endif %} for {{ interest }}
{% endfor %}
{% endif %}
{% endfor %}

Is there a way for it just to print the lines without adding all the
extra blank lines when interests = 0?

Jinja basically uses django's syntax, but (if my memory is correct) it 
allows you to do more things than django's templates allows you to.


Is it faster? I thought there were people trying to bring jinja into 
django as it is good and fast. If it is faster, it would probably be 
because people are making a dedicated effort at making it fast. Multiple 
projects are using jinja, so there's a good chance that the combined 
effort *could* make it faster.


I don't know from experience, though, *if* it is faster.

inherit adminSite and get 404 when click model

[brian]

I have multiple models.  I'm trying to create an admin site for all
models (using admin.site) and an admin site for each model (by
inheriting from AdminSite).

The admin.site is working as expected.  The AdminSite will load the
app as normal but when I click on the model, I get a 404 error.

I'm following very closely 'How to have 2 different admin sites in a
Django project'(http://stackoverflow.com/questions/3206856/how-to-
have-2-different-admin-sites-in-a-django-project).

Here is the pseudo code of what I'm doing:
model.py
---
class myBaseModel(models.Model):
first_name   = models.CharField( max_length=100)

class myModel1( myBaseModel ):
class Meta(myBaseModel .Meta):
verbose_name = 'my model 1 info'

class myModel2( myBaseModel ):
class Meta(myBaseModel .Meta):
verbose_name = 'my model 2 info'
---

admin.py
---
admin.site.register( myModel1)
admin.site.register(myModel2)
---

myModel1Admin.py
---
class myModel1Site(AdminSite):
pass

adminModel1 = myModel1Site()
adminModel1.register( myModel1 )
---

url.py
---
from django.contrib import admin
admin.autodiscover()

from .myModel1Admin import adminModel1

urlpatterns = patterns('',

url(r'^masterAdmin/', include(admin.site.urls)),
url(r'^model1Admin/$', include(adminModel1.urls)),
)
---

The url   is working as expected.  When I go to
 the page looks as I would expect but when I click on
'my model 1 info' I get a 404 error.

Re: How do I apply a filter in a custom template tag?

[Doug Ballance]

I'd like to see you model structure, but based on what I think it is:

class Entry(model.Model):
categories=models.ManyToManyField(Category)

class Content(models.Model):
entry=models.ForeignKey(Entry)

You have a Content Instance
You want to see other entries belonging to one or more of the
categories for that Content instances Entry instance

You could do a custom template tag like yours:

{% get_related_entries content_instance.entry  as related_entries %}

That tag would do something like the following :

#fetching primary key only since we don't need the whole thing
category_ids=content_instance.entry.categories.values("pk")
context['related_entries']=Entry.objects.filter(pk__in=category_ids)

That would work, but my choice would probably be to add a method to
your Entry class.

class Entry(models.Model):
categories=models.ManyToManyField(Category)

def related_entries(self,**filters):
return
Entry.objects.filter(pk__in=self.categories.filter(**filters).values("pk"))

That way you don't need a tag at all.  Just do:

{% for related_entry in content.entry.related_entries %}
...
{% endfor %}

Re: same form model with separate admins and data

Hi  Landy,

I'm seeing separate database tables created.  The tables that are

Thank you for your help  You have given me a lot of great ideas.

Where I have done this (reluctantly) has been in the form (or perhaps it was
the field) clean method, where self is the form. I am not sure why in your
case you believe that to be not practical.


The field's clean method does not have access to the form; but the 
value-changing logic should go into the field code because I want to 
re-use the field on multiple forms.  Well, I guess that's just not 
possible with Django's form framework. I'll have to find some workarounds.

Re: Using South HOWTO create an instance of a model from a different app during DataMigration

*UPDATE:*

I was able to resolve the problem by looking up the contenttype manually so,

ct = orm['contenttypes.ContentType'].*objects.*get(app_label="blog",
model="Post")

Thanks Tom & Andrew (at south user listserv) for helping with this.

Re: Using South HOWTO create an instance of a model from a different app during DataMigration

[Chintan Tank]

Tom,
I tried looking up the content_type and then using it, but it still throws
errors.

*1. I tried*

ct = ContentType.objects.get_for_model(Post)
chapter = orm.Chapter(rank=1, content_type=ct, object_id=blog.id)

*It gave error,*

ValueError: Cannot assign "": "Chapter.content_type" must
be a "ContentType" instance.

*2. I tried*

ct = orm['contenttypes.ContentType'].objects.get_for_model(orm['blog.Post'])
chapter = orm.Chapter(rank=1, content_type=ct, object_id=blog.id)

*It gave error,*

AttributeError: 'Manager' object has no attribute 'get_for_model'

*3. I tried*

ct = orm['contenttypes.ContentType'].get(app_label="blog", model="Post")

# I also tried setting model in the above get method to be lowercase.

chapter = orm.Chapter(rank=1, content_type=ct, object_id=blog.id)

*It gave error,*

AttributeError: type object 'ContentType' has no attribute 'get'

*BTW*, I am using *South 0.7.3.*

How do I apply a filter in a custom template tag?

[Josh]

I'm trying to retrieve a m2m relation from a blog entry. It should give a 
list of entries with the same categories. Below works when I work in the 
shell.

from content.models import Entry
qs = Entry.objects.all()
obj = qs[0]
related = Entry.objects.filter(categories=obj.categories.all())


The obj simulates a single Entry in a template for use in the shell.

I'm trying to put this in a custom template tag, so a list of related 
entries can be shown with a blog entry. I cooked up the following:

{% load content_tags %}
{% get_related_entries content.entry from*object.categories.all
* as related_entries %}
{% for item in related_entries %}
{{ 
item.title }}
{% endfor %}

This isn't working though. I'm not sure how to do this, even after 
(re)reading Django-books and documentation. When I don't apply a filter and 
the following in the Node render() works:

context[self.varname] = self.model.objects.all()

Obviously I get a list of all entries, without any filter. I'm pretty sure 
it has to do with the object.categories.all (which is a list of all 
categories) in my template tag and the use of it in the parser/Node. How can 
I achieve this? 

PS:
I didn't include any of my (now many) variants of code I tried on purpose. I 
suspect I'm following an entirely wrong approach and don't want to focus 
attention at wrong code.

FYI the terminology of "importing" an app into a template is a bit
confused/confusing, we don't, in Django, import apps into templates. There
is no concept in Django that quite matches those words, although loading
custom template tags from an application comes close.

Your template code fragment uses a context variable named "form". That
template code works for your login/logout pages presumably because your
login.views.index and login.views.logout_view supply the correct "form"
variable in the context used to render the template.

Including that fragment in your base.html file means that you are expecting
every view that renders a template which ultimately extends from base.html
to provide a context variable named "form" that is the login/logout form.
That's not working because apparently you've got some other views that also
use this name "form" for some other kind of form, and that other form is
what you see rendered in this template fragment instead. If you have views
that provide no variable named "form" in the context, then this bit of
template code will show no form at all.

Essentially by including this HTML fragment in your base template you have
put the template-side of your login/logout app into all your templates, but
that does not accomplish the necessary piece of also incorporating the
Python code side of populating the template context with the correct
variables for the template side.

What you probably want to be doing is creating a custom template tag (to be
specific, probably an inclusion tag) in your login/logout app. You can then
use that template tag in your base template to render the login/logout form.
See the docs here:
https://docs.djangoproject.com/en/1.3/howto/custom-template-tags/

 Is there any way to use a different value for a field when re-displaying
 a form? I.e. if a user enters '42' into an IntegerField but made the
 other fields not validate, how could that IntegerField be re-displayed
 with '43'?


  Change the value in the form's data dictionary.

Because you've past request.POST directly to the form as the data dict. You
can instead pass a copy when instantiating the form, then you will be able
to modify the copy.

Where I have done this (reluctantly) has been in the form (or perhaps it was
the field) clean method, where self is the form. I am not sure why in your
case you believe that to be not practical.

If you want to change the value displayed for a field in the form, you'll
either need to change the value in the data dictionary or change the guts of
how the form displays itself. The former is the easier choice, imo.

Displaying form from app in other view.

[Petey]

I have a login/logout application - it works within its defined view 
(login/views.py) and templates (templates/login/index.html).

I want to port this app so it will be displayed in base.html. The main 
problem is that I don't really know how to import this app correctly to 
base.html.

If I use code pasted below it does only display correctly on localhost/login 
page instead of localhost. On pages containing other forms it will display 
other form instead of my login form.

How can I import login form to global template (base.html) and how I can 
differentiate forms from different apps?

{% csrf_token %}
{{ form.as_p }}



urls:
(r'^login/$', 'login.views.index'),
(r'^logout/$', 'login.views.logout_view'),

Change the value in the form's data dictionary.

Thanks Karen but that's not easily possible because that's an immutable 
QueryDict. Plus, afaik, fields can not access form instances so this 
code would have to live in the form subclass -- not practical in my use 
case.
